Reef lubricants and Rust Inhibitors

[siggy]

In a recent thread I had mentioned using NeoSporin as a o-ring lubricant. Any thoughts on the Anti bacterial agents and effects in a reef environment also the ointment base is unknown to me.
this is the tread that spurred the discussion. https://www.reef2reef.com/threads/c...e-wet-sides-around-shaft.442113/#post-5038352

I use a very small amount of molykote 111 from BRS to lubricate O rings.. also trident food grade silicon works well

Vaseline

Definitely not Vaseline, or any petroleum based product. These will cause the rubber to swell and fail prematurely.

Use non-petroleum based Plumber's grease, the product above, or what I use.....Leslie's Pool and Spa Lube....seven bucks gives you a lifetime supply..

The base for Neosporin is Vaseline with some other stuff.
The original ointment contains three different antibiotics: bacitracin, neomycin, and polymyxin B, in a relatively low-molecular-weight base of cocoa butter, cottonseed oil, sodium pyruvate, tocopheryl acetate, and petroleum jelly.

I like Molykote 111

I bought a tube of Haynes food grade silicone cheap from Amazon. Enough to last a very long time

I definitely wouldn’t use neosporin as a lubricant.
